Romulan and klingon laws never applied? Really? And where did you get that - aside from your wishful thinking leading to hand-waving? The baku trespassed on a romulan planet - meaning romulan law was applicable. Then the planet became klingon - klingon law applied. Then the planet became a federation planet - meaning federation law applied. Now - about these laws: Adverse possession is a law mostly applicable in modern liberal democracies. Throughout human history, the majority of societies were oligarchic. Do you actually think the nobles allowed the peasants to acquire their land simply by occupying it? Good luck with that. Do you actually think klingon and romulan laws allow trespassers to acquire romulan and klingon territory by trespassing on it? lol Of course, the romulans and Klingons never found the baku, in order to conquer them, turning them into imperial subjects. So much for the baku not hiding (them hiding was even established in the movie - see below). Now you're walking the path of the legalisms, I see. First - that planet was NOT ownerless when the baku came to it. It was a romulan planet, then a klingon planet. Second - the baku actively tried to hide in the briar patch. NOT public possession by any standard. Even if the baku would not have actively tried to hide, they would NOT have exercised public possession if they didn't exercise even minimal diligence in making their claim known - as in, a beacon announcing their presence, or seeing if there are alien (romulan/klingon/federation) patrols in the area and contacting them; or contacting any ship they see in the area, exploring a little in order to ascertain the status of the planet, etc. NO public possession (no useful possession - this includes several more conditions) = NO adverse possession. And now, you've turned to stereotyping and simplistic straw-men. For example - Cestus III; the federation not enforcing a claim to that world would result in its strategic position seriously compromised, in possible millions/billions of federation citizens dead or conquered in the future. In these conditions, enforcing a claim to Cestus III IS the right thing to do. The powers in the trekverse - klingons, romulans, dominion, tholians, borg, etc, etc - make soviet russia or 'the hermit kingdom' look very tame. Some of them make nazi germany, the mongol hordes or 'insert the nastiest historical empire you can think of' look very tame. You think that, in that universe, not using real-politik at least some of the times (such as, when the future of billions is in the balance) will somehow turn your nation into a beacon of security and prosperity, as opposed to causing suffering and death for your people? lol. Of course, with the baku affair, the federaiton has BOTH the legal right and the muscle to enforce that right. And the moral high ground. PS: The baku were hiding in the briar patch from the universe, essentially (see their backstory from the movie, etc). In 'enterprise', the augments briefly contemplated hiding in the briar patch, as well - as the name indicated, it's a pretty good hiding place. Dougherty expressly told Picard the baku are not native and the prime directive doesn't apply. How did the federation think the baku got to the planet? Not specified in the movie; there are several possibilities: the federation knew the baku are not really primitive, aliens brought the baku there and then disappeared (this happens often in the trekverse), etc. Next time, watch the movie before coming with your unsupported claims.
